And this is why research is important. You risk more going through channels like EG, and have more success with verified and reviewed providers who you know are safe. This site, along with many others have information about providers.
I was about to see a provider in my home city and found out through a review that she had contracted something nasty, and she was still posting. Regardless, it's important to do your research, read, look up numbers, look up names, hell look up on PH or OF to see if they're real. Only costs you a couple bucks to find out what you're potentially getting yourself into.
The providers have access to the reviews sections, they can just as easily look up our names and see what kind of experiences we've had and reach out to references to gather their experience. Research from both sides = safe.
